During the reign of Sultan Omar Ali Saifuddin I, he became renowned for his bravery in the battle against Datu Teting-led Sulu forces in 1775.

After seeing the defeat, the Sultanate of Sulu has renounced its claim to the region north of Brunei became quite afraid and hasn't followed the deal to this day.

[8][9][10] The complex geology, faulting, and internal reservoir cross-flow of the Ampa Field provide challenges despite its well-understood reservoirs.These problems are addressed by research employing 3D models and analytical calculations.

[11][7] SWA-1 was used for the discovery, which revealed a shallow reservoir with a fluctuating condensate percentage, a relatively high solution gas–oil ratio, an API gravity of 40°, and an initial oil viscosity of 0.35 cp.

[1] In order to generate revenue from these deposits, Brunei had to surmount significant obstacles including vast distances to prospective markets, an untested technology for gas liquefaction, and a lack of expertise in LNG transportation.

[6] BSP granted a three-year contract to McDermott International to transport and build pipelines and umbilicals for the Champion and Ampa Fields offshore Brunei.

These included the installation of two new pipelines, a centralised crude stabilisation facility, and an upgraded distributed control system—all of which had negligible impact on the delivery of oil and gas.
